Like the artificial phoenix bird, gene treatment has soared from the ashes and is dispelling its wings.
September 17 marked 20 years since the demise of 19-year-old Jesse Gelsinger in a gene treatment trial. That catastrophe halted the fledgling field, with the outlook worsening when, soon after, boys with an open inherited immune weakness developed leukemia when a gene treatment went off course.
The momentum that had been slowly building since the initial clinical trial in 1990 fizzled.
Researchers have refurbished the viruses that came in working manuscripts of genes, and slowly clinical trials began again. But it acquired until late 2017 for the initial FDA permission of gene therapy: Luxturna, for blindness because of mutation of a gene named RPE65.
My book The Forever Fix: Gene Therapy and the Boy Who Saved It, coming from 2012, chronicles the past of the field as a backdrop to the Luxturna story. The guy, Corey Haas, was 8 when he was treated in 2008. He has made amazing growth.
Seven years after, Amy Reif notes that her daughter, who was dealt with in the month of July 2018 when she was 7, can glimpse in a dimly-lit room where once she could not see at all.
She can reside outside to play in the twilight at dusk much extended than she could preliminary to Luxturna. She can glimpse a rainbow, stars, lightning bugs. She across-the-board just gets around more effortlessly, shows more confidence, and is more convinced of herself.
The second and most new gene therapy approval, Zolgensma, is for spinal muscular dystrophy atrophy, treats aa situation that is generally lethal in infancy.
FDA ratified it in May 2019, after Novartis grabbed it up from biotech company AveXis, which commercialized research from Nationwide Children’s Hospital. Academia to tiny biotech to huge pharma is a common trajectory in drug improvement.
